In 1827, she retired from the stage for a time, being unjustly accused of complicity in the murder of Johann Conrad Blank (de) by Severin von Jaroszynski (de). She wrote several plays: Sylphide, das See-Fräulein (1828), Der Branntweinbrenner und der Nebelgeist (1829), and Kleopatra (1830).

Krones died in Vienna after a short but serious illness, aged only 29. She was buried at the St. Marx Cemetery, but in 1930 was exhumed and reburied in an honorary grave in the Vienna Zentralfriedhof.
